Description

The Chevrolet Performance LS364/450 6.0L is a high-performance long-block crate engine for upgrading early LS-powered vehicles. It features a cast iron block, durable rotating assembly, high-lift LS6 camshaft, and LS3 aluminum cylinder heads, delivering 452hp and 441 lb.-ft. of torque. Designed for fuel injection, it uses early-style 24X crankshaft and 1X camshaft sensors for easy retrofitting into Gen III LS-powered vehicles. Sold as a long-block, it requires transferring induction, ignition, and front-end accessory drive systems, or custom components. An LS3/L92-style rectangular intake manifold is necessary.
